REPAIR DEVICE.

Application filed October 16, 1923. Serial No. 668,868.

To all w/zom it may concern:

Be it known that 1, MAX ANCHELEVICH a citizen of the United States,residing at Evansville, in the county of Vanderburg and State ofIndiana, have invented certain new and useful Improvements in RepairDevices, of which the following is a specification.

This invention relates to a repair device for radiators designedprimarily for use in connection with automobile radiators of thehoneycomb type, but it is to be understood that a repair device inaccordance with this invention can be employed for any purposes whereinit is found applicable, and has for its further object to provide, in amanner as hereinafter set forth, means for repairing a radiator leak,when the radiator tubes are polygonal shape in contour withoutnecessitating the removal of the radiator from the car, and with themeans so constructed whereby it can remain indelinitely in position ifdesired.

Further objects of the invention are to provide, in a manner ashereafter set forth, a radiator repair device. for stopping leakage andwhich is simple in its-construction and arrangement, strong, durable,thoroughly eflicientiin its use, readily applied in operative relationwith respect to the radiator tubes and inexpensive to manufacture.

With the foregoing and other objects in view, the invention consists ofthe novel construction, combination and arrangement of parts, ashereinafter more specifically described and illustrated in theaccompanying drawings, wherein is shown an embodiment of the invention,but it is to be understood that changes, variations and modificationscan be resorted to which come within the 'scope of the claims hereuntoappended.

In the drawings wherein like reference characters denote correspondingparts throughout the several views Figure 1 is a fra mentary view, insection, of a radiator showing the adaptation therewith of a repairdevice in accordance with this invention.

Figure 2 is a grouped perspective view illustrating the elements of therepair device disassembled.

It is of course well known that honeycomb radiators consist of a chamberof relatively small thickness and with the chamber provided with frontand rear parallel walls, formed with tubular passages through which thecooling air passes. 1n radiators of this character, the liquidcirculates about the tubular passages and the air passes through them.When a leak occurs in the radiator, water will discharge therefrom andthe water circulation for the engine will be destroyed, under suchconditions the engine will become heated and if it continues to operatewithout the water cooling system performing its function, serioustrouble will result. A repair device, in accordance with this inventionis employed for elliciently stopping a leak in the wall of a tubularpassage so as to prevent .the discharge of water from the radiatorwhereby the water cooling system will function.

Referring to the drawings in detail, 1 denotes a radiator of thehoneycomb type and with the tubular passages 2 thereof polygonal, butthey can be of any desired shape in cross section.

The repair device, in accordance with this invention, consists of a pairof closure members and a coupling member. One of the closure members isindicated generally by the reference character 3, and the othergenerally by the reference character l. The couplingniember is referred,to

shape in cross section and provided with a lengthwise extending socket7, having the wall thereof threaded throughout. The length of thesocket. T is substantially the same as the length of the stem 6. Theouter end of the stem (5 has formed integral therewith a head 8 whichprojects from each ofthe side faces of the stem 6 aud'has its inner face9 fiat throughout, so that when the closure member 3 is in operativeposition with respect to a tube 2, the inner face of the. head 8 willabut throughout against the radiator l, and as the head 8 is of greatersize than the tube 2, one end of the tube 2 will be completely closed bythe head 8, as shown in Figure 1.

The closure member 4 comprises a substan tially elongated hollow stem10, which is polygonal shape in cross section, and which forms apolygonal shape socket 11 for the lUU reception of the stem 7 when theclosure member 3 is mounted in operative position, as shown in Figure lof the drawings. Formed integral with one end of the stem. 10, is a flatcircular disk 12 which is larger than the head 8, and said disk 12,,whenthe closure member is mounted in operative position, abuts against theother side of the radiator 1 for the purpose of closing the other end ofthe tube 2, as shown in Figure 1. The disk 12, is of materially greatersize than the size of the tube 2 and both faces are flat throughout. Thedisk 12, centrally thereof, is provided with an opening 13. The lengthof the stem 6 or a stem 10, is less than the length of the tube 2. Thestems 6 and 10 may be of the same length or of any suitable lengthdesired.

When the closure members 3 and 4 are arranged in operative position withrespect to the tube 2, for the purpose of closing the ends thereof, thestem 6 is telescoped by the stem 10.

The coupling member comprises a substantially elongated cylindrical stem1i, arovided with peripheral threads throughout, as indicated at 15, andthe outer end of the stem. 15 is provided with a head 16 having itsinner face fiat throughout, as at l7, and which abuts when the couplingmember is in operative position against the tint outer face of the disk12 in a manner shown in Figure 1. The closure members 3 and t, aredetachably coupled together, when arranged in operative position withrespect to the tube 2, through the medium of the coupling member 5, andthe latter when in operative position extends through the opening 13 andhas threaded engagement with the wall of the socket 7 in the member 6shown in Figure l. The outer face of the head 16 is grooved, as at 18,for the reception of a suitable instrument, forthe purpose of shiftingthe coupling member 5 to and from engagement with the threads of thewall of the socket 7.

When using the repair device, the closure member 3 is first inserted inthe tube 2 from one end thereof, after which the closure member a isinserted in the tube 2 from the other end thereof and is arranged intelescopic position with respect to the stem (3. When the closuremembers 3 and t are arranged in the position, as stated, the coumeme-epling member 5 is then inserted through the opening 13 and shifted untilits threads 15 engage with the threads of the socket 7 whereby theclosure members 3 and 4 are detachably coupled together in operativeposition for the purpose of closing or sealing the ends of the tube 2.

The preferred embodiment of a repair device, in accordance with thisinvention for the purpose of stopping leaks in a radiator without theremoval of the radiator, is as described and illustrated; but it is tobe understood that changes in the details of construction can be hadwhich will fall within the light of the invention as claimed.

WVhat I claim is 1. A repair device for the purpose set forth comprisinga pair of telescopic closure members each having its outer end providedwith a head, each of said members in-.

cluding a shank, one of said shanks provided with a socket for thereception of the other of said shanks and the last mentioned shankprovided with a socket formed with a threaded wall, and a removablecoupling member including a threaded shank extending into the lastmentioned shank and engaging the threaded wall ofsaid socket fordetachably connecting said closure members in operative position, theshanks of said closure members being polygonal in cross section and theshank of said coupling memher being cylindrical.

2. A repair device for the purpose set forth comprising a pair oftelescopic closure members each having its outer end provided with ahead, each of said members including a shank, one of saidshanks'provided with a socket for the reception of the other of saidshanks and the last mentioned shank provided with a socket formed with athreaded wall, and a removable coupling member including a threadedshank extending into the last mentioned shank and engaging the threadedwall of said socket for detachably connecting said closure members inoperative position, the socket in the shank of that closure member whichreceives the shank of the other closure member being polygonal in crosssection, and the other of said sockets being cylindrical.

In testimony whereof, I attix my sign-a ture hereto.

MAX ANCHELEVICH.
